Ffrwd Fawr Waterfall

The Dylife Gorge, located near Dylife, Powys, Mid Wales, was carved by the action (and aftermath) of the last Ice age. It is headed by the Ffrwd Fawr Waterfall. Before the last Ice age, the River Twymyn did not flow through the valley. When the valley was filled by a glacier, the ice ground out a U-shaped glaciated valley. When the glacier that filled the valley melted the Twymyn started to run down the wide channel left behind and the fast flowing river further eroded the valley, cutting the V-shaped gorge as seen today.The long-distance footpath Glyndŵr's Way (Welsh: Llwybr Glyndŵr) passes nearby.

Dylife is a former mining settlement in Powys, Wales, located at the head of Afon Twymyn in the Cambrian Mountains, one mile west of the road between Llanidloes and Llanbrynmair (B4518).

During the late 19th century, as mining declined after the 1860s so did Dylife's population. The remaining buildings are two former chapels converted into homes and the Star Inn.

Commins Coch is a small village on the A470 in the county of Powys in Wales. It is part of the Glantwymyn community. Commins Coch is notable for the narrow bridge set at right angles that crosses the Afon Twymyn. The size and angle of the bridge restricts all traffic to crossing one vehicle at a time and it can be a serious problem for articulated lorries to cross. Commins Coch is also the site of one of the 1970s holiday cottages allegedly burnt down by Meibion Glyndŵr during its campaign against English incomers. The cottage, now restored, can be seen on the right when leaving the village travelling East. Previously served by Commins Coch Halt railway station on the Cambrian Line.
